Im so glad I paid my rent

My phone battery is acting up on me and it's not staying charged it started after I return from the ER department from hell. I have to buy me a new phone I had this phone for a while now never damage it . It just won't stay at 100% it's like the stock market. It's stressing me out and I need my phone to watch videos to relax and do work .might be I. And out for a while. I hate struggling!!!!!
